A basic pendulum is a mass at the end of a string that swings back and forth. It seems simple, and it appears in most introductory physics textbooks. But it's not a trivial problem to solve for the ...

Gravity is, at heart, a mystery. Yes, we can talk about curvature of space-time and perhaps make analogies with stretched rubber sheets. But we don’t know why mass causes space-time to curve. To put ...

The Foucault Pendulum illustrates the rotation of the earth. It is not constrained to stay in a fixed plane like a clock pendulum, but instead its ordinary pendulum motion is free to change direction ...

Miami’s physics department may have gotten a new house last year, but it never really felt like home — until now. Missing was the department’s famed Foucault Pendulum. It couldn’t be moved from Culler ...

The first Foucault’s pendulum I ever saw was at the Franklin Institute in Philadelphia, the city where I was born. The pendulum hung in a stairwell. Its wire was attached to the ceiling four stories ...
